Title: Fruit and vegetable decapping machine
IPC: A23N15/02
Filed: 1975-05-13
Abstract: A machine for detopping fruits and vegetables, specially suited for the decapping of strawberries by severing the top therefrom, comprises an endless upwardly-inclined loop type conveyor mounted on a sub-frame which is in turn mounted on a main frame for horizontal orbital motion relative thereto. The conveyor consists of a receiving station section inclined to the horizontal so that already decapped product discharges against the travel of the conveyor, and a severing station section at a higher level than the receiving station section, a downwardly-extending discharge section and a return section. The conveyor consists of parallel rollers alternate ones of which are positively driven by pinion gears engaging rack members at the side, so that co-operating pairs will grip the tops. Only product that has been so gripped can be conveyed upwards by the conveyor and presented to a transversly moving endless band severing knife at the severing station. The orbital motion causes the product to be orientated into a position which facilitates gripping of the caps by the cooperating roller pairs.

Patent ES-452958-A1 (ES)
Title: Pressure release device
IPC: H01M2/12
Filed: 1976-11-03
Abstract: This device is arranged in the container wall in order to reduce an internal pressure prevailing in a container, preferably a container (5) of an electrochemical element, and, in a deformation region (11, 12) of said container wall, has at least one weak-point zone (13) which tears in the event of expansion resulting from excessive internal pressure. In order to achieve very precise matching to the desired bursting pressure despite low production costs, hermetic sealing and corrosion resistance, the weak-point zone (15) is slightly deformed and is provided between two adjacent deformed regions (11, 12) of the container wall. If the predetermined container internal pressure is exceeded, the two deformed regions (11, 12) are expanded and the weak-point zone (13) located between them is subjected to expansion until it fractures.

Title: Semi-unitized shaft seal and method
IPC: F16J15/32
Filed: 1977-03-08
Abstract: A two-part, separable, semi-unitized shaft seal for sealing between a housing bore and a relatively rotatable shaft extending through the bore and comprising a metal wear sleeve member and a sealing member assembled onto the wear sleeve member for transportation, shipping and installation of the seal as a unitized seal. However, when the housing and shaft are disassembled, one of the two seal parts remains with the housing and the other part remains with the shaft, whereby each part can be examined and replaced, if necessary, without discarding the entire seal. One seal part press-fits onto one of the housing and shaft and the other seal part forms an elastomeric interference fit on the other of the housing and the shaft.
Patent ES-461372-A1 (ES)
Title: Torque analog of a series wound DC traction motor
IPC: H02P5/00
Filed: 1977-08-05
Abstract: Apparatus for electronically simulating the response of a direct current traction motor to predetermined operating states whereby there is provided a resultant signal representative of the torque that would be produced by an actual motor operating in the prescribed states. The apparatus calculates E per RPM for the simulated motor from measured values of available armature voltage and armature velocity. A function generator thereafter converts the E per RPM signal to a signal representative of the motor field current based upon known values for the simulated motor. The field current signal is converted to an armature current signal by a circuit which responds to the motor commanded state of field weakening to compute the instantaneous ratio of armature current to field current under the commanded conditions and thereafter multiplies the field current signal by that ratio to obtain a signal representative of armature current. Multiplication of the armature current signal by the E per RPM signal then yields a signal representative of the torque which would be developed by the simulated motor.

Title: Method and apparatus for golf practice and instruction.
IPC: A63B57/00
Filed: 1978-08-25
Abstract: A method of practicing and teaching golf comprises the step of projecting a golf ball into a ball hitting zone during a player's swing of a golf club, while the head of the club is approaching the hitting zone. The ball is projected to arrive in the hitting zone, in the path of the club head, immediately prior to sweep of the head into the zone. The apparatus for practicing and teaching golf comprises a station which provides a hitting zone through which the head of a golf club is swept by a player performing golf swings. A projection device is operable during the player's club swing, while the club head approaches the hitting zone, to strike a ball and thus pop it quickly into the zone in the path of the club head when the head sweeps into the zone.

Title: Time division multiplex telephone exchange
IPC: H04Q11/04
Filed: 1978-11-17
Abstract: In a TDM telephone exchange, it is necessary when setting up calls to take account of the time taken for a PCM code combination to negotiate the exchange's switching network. A path supervision device, addresses the input and output ends of that connection, and stores input and output PCM combinations. Each input combination is compared successively with all output combinations, and from the times at which identity is detected, the shift in time caused by the passage through the network is determined. Any variation in this shift causes: (a) an evaluation of the new shift, and (b) the recording of data representing the new shift plus the time at which the change occurred. Supervision of one connection ceases either when an allotted time has elapsed, or after a preset number of unsuccessful identity tests. The recorded data are analysed and a statistical reading is sent to the central control.

Patent ES-8105907-A1 (ES)
Title: Improvements in or relating to timing recovery for modems.
IPC: H04L27/38
Filed: 1980-09-18
Abstract: The improvements relate to a technique of timing recovery from the line signal by envelope detection using double bandpass filtering prior to detection to improve the power ratio of the recovered timing signal to the interfacing byproducts of the squaring process. In addition the difference frequency components which are used to provide the desired timing signal, there are not only the sum-frequency products but also the products of squaring the individual bandpassed signal components, some of which may be in the same frequency region as the difference frequency signal. This problem is avoided by taking the outputs of the two bandpass filters (F4, F5) and applying them severally to the two input ports of a four-quadrant multiplier (P). The output from the multiplier will then comprise only sum-frequency and difference-frequency products, the latter being easily separable (F3) and providing the desired timing recovery signal free from impairments.

Title: Device for cleaning conveyor belts.
IPC: B65G45/00
Filed: 1980-12-24
Abstract: A cleaning device for cleaning a conveyor belt comprises a cleaning member mounted on a lever which can move angularly about a pivot axis extending transverse to the run of the belt, the lever also carrying a pressure member arranged to contact the face of the belt opposite to the face to be cleaned, the cleaning member being urged into contact with the surface of the belt by the reaction of the pressure member to movement of the belt causing angular movement of the lever about its pivot axis. The pressure member and cleaning member may be resiliently urged towards one another in the direction of the axis of the lever to enable wear of the cleaning member to be compensated automatically while reducing the angle through which the lever pivots during the useful life of the cleaning member.
Patent ES-8201423-A1 (ES)
Title: Automatic roll-up device for a safety belt
IPC: B60R22/36
Filed: 1981-03-12
Abstract: Automatic roll-up device for retarding movement of a safety belt when a predetermined acceleration or deceleration is exceeded, combined with a braking- or clamping device in which the retarded belt is arrested. The roll-up device has a retarding mechanism which blocks a control disc causing braking of the belt roller. This causes a change in movement of the belt which activates the braking- or clamping device. The latter immediately arrests movement of the belt and absorbs any pulling forces which would have been exerted against the retarding mechanism. The roll-up device can be of light-weight construction.
